Application Modernization

Who Should Modernize?

Who should modernize?

All software applications:

  • that were developed between 1980s – 2010, using legacy technologies that are no longer supported
  • that are in the maturity/decline phase of their product lifecycle

Why should you modernize?

Legacy applications must be modernized, because:
  • non-responsive UI makes rendering on new class of devices impossible
  • interdependent business/data logic, and large monolithic code bases created unmanageable, spaghetti code; making even incremental changes a herculean task
  • inflexible and closed architecture that hinders web enabling and integrations
  • of inability to scale due to lack of separation of concerns in traditional 2/3-tier architectures
  • unmitigated risk of unsupported software with closed architecture, and accumulated technology debt
  • they cannot be deployed using modern cloud-based infrastructure, or leverage opportunities to offer software-enabled services in a SaaS environment
  • they cannot leverage emerging technologies such as AI/ML, AR/VR, IoT etc. to meet changing enterprise needs
  • business landscape demands faster time-to-market and business agility with shorter dev, test, and deploy cycles; not possible with tightly-coupled development and delivery processes
  • in a fast-changing market, to remain competitive, modern stacks are needed along with the ability to support changing regulations and compliance burden
  • of competitive pressures to increase operational efficiency by reducing technology debt, lowering TCO, and delivering higher ROI

What is Application Modernization?

Application modernization is the process of refactoring, reengineering, and repurposing legacy applications, to meet the enterprise needs in a modern business and technology landscape. There are three distinct aspects to application modernization:

  • Technology Modernization is upgrading various elements of the software stack including programming languages, IDEs, libraries, databases, and OS. This could be either with latest versions within the same technology stack or could be replacing with more modern, robust stacks.

  • Architectural Modernization is the process of redesigning and re-architecting legacy, monolithic applications into flexible, distributed, and modular applications using modern architectural paradigms.

  • Deployment Modernization is the process of transforming how software applications are developed, deployed, and supported. Depending upon the specific context of legacy applications, it could vary from web-enabling to complete cloud transformation and delivering SaaS.
